Prince Peter (Pyotr) Alexeyevich Kropotkin (9 December 1842 - 8 February 1921) was one of Russia's foremost anarchists and one of the first advocates of anarchist communism: most of his life he advocated for a communist society free from central government. Because of his title of prince and his prominence as an anarchist in the late 19th and early 20th centuries, he was known by some as "the Anarchist Prince". Some contemporaries saw him as leading a near perfect life, including Oscar Wilde, who described him as "a man with a soul of that beautiful white Christ which seems coming out of Russia." He wrote many books, pamphlets and articles, the most prominent being The Conquest of Bread and Fields, Factories and Workshops, and his principal scientific offering, Mutual Aid: A Factor of Evolution. He was also a contributor to the Encyclopedia Britannica Eleventh Edition
